Paten-ted Mar, 27, 1917. 51,778. Divided and this application filedOctober 7,

19118. Serial No. 124,392.

To all whom t may concern:

Be it known that l, BENJAMIN F. GOLL- MAR, a citizen of the `UnitedStates, residing at Baraboo, in the county of Sauk and State ofVisconsin, have invented new and useful Improvements in Vapor-Stoves, ofwhich the following is a specification.

My present invention pertains to vapor stoves; and it consists in aconstruction and relative arrangement of stove body, burner, and cookingunit, designed more particularly for embodiment in the stove disclosedin my contemporary application liled April 17, 1916, Serial Number91,778, of which this application is a division.

ly present invention will be fully understood from the followingdescription and claims, when the same are read in connection with thedrawing, accompanying and forming part of this specilication, in which:

igure l is a central vertical section through the improved stove body,the burner and the frying-pan unit.

Fig. 2 is a View, partly in front elevation and partly in section, ofthe oven unit. Fig. 8 is a similar view of the pot unit.

Fig. 4 is a detail transverse section taken through one of theventilators.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

y improved stove is preferably portable in character, and comprises ashallow body 1, open at its upper side, and legs 2, preferably of gaspipe, arranged under and supporting the body.

In the body 1 is a burner space which ocinterior of the body, and ispreferably surrounded by a channel-iron or other frame 4, and in saidburner space is disposed a horizontally-disposed vapor or gas burner 5,designed to be supplied with vapor or gas through a conduit 6, andhaving horizontal burner tubes 7 and caps 8 at the ends thereof, asfully shown in my contemporary application before alluded to.

For supporting combustion in the burner space, the body 1 is provided inits bottom wall with one or a plurality of groups of apertures 10, andone or more slidable apertured dampers for controlling-- c., regulatingthe size of the apertures 10, as occasion demands. It will also beobserved that urner space is provided in its side walls with protectedventilators 12, and that similar ventilators 13 and 14 are provided inthe side walls of the pct unit, Fig. 3, near the top thereof, and in thetop wall of the oven unit, Fig. 2, adjacent to the sides of the saidoven unit. The said protected ventilators are of the same constructionand therefore a detailed description of the one shown in F ig. et willsuffice to impart a deti nite understanding of all. The ventilatorspecifically referred to comprises a slide 20, movable in guides 21 andarranged to control an opening 22 in the wall, and an interior guard 23attached to said wall and open at each end and closed on the sides. Whendeemed expedient, the ventilators in the bottom wall of the body, belowthe burner space 3, may also be of the protected type just specificallydescribed.

he stove without the protected ventilators in the body 1 as describedcannot be successfully operated in the open air because the heat andproducts of combustion cannot circulate. It will be noted, however, thatwhile the protected ventilators admit ample atmospheric air to supportcombustion and to promote circulation of the heated air in the body land to regulate the heat in said body, they preclude the entrance of anydrafts that would be calculated to interfere with the normal and properworking of the stove. l would also have it understood thatl when thestove is used for frying, the side ventilators in the body 1 give riseto rapid heat circulation conducive of a successful frying operation,and prevent dead ends or pockets suoli as would interfere with thoroughheat circulation and proper operation of the stove.

is shown in Fig. l a frying pan unit 30 is removably arranged on thebody 1; said frying pan unit being ianged to prevent casual displacementthereof.

The scheme of my invention contemplates the use of the frying pan unit30, the oven unit 32, Fig. 2, and the po't unit 33, Fig. 8,interchangeably on the body 1 so that each .may be used over and incombination with a single heating means.

The oven unit 32 is provided with outer walls made up of sheet-metallayers 34 and an interposed asbestos layer 35, and when desired. ordeemed expedient the outer walls of 'the body 1, may be similarlyconstructed. rlhis latter, however, l have deemed it unnecessary toillustrate. The said oven unit 32 is flanged at 36 to lit on the body 1,is open at its bottom, and is provided in its closed top with protectedventilators 12 similar to the ventilators 12 before referred to.Arranged in and forming a permanent part of the oven unit is afood-receiving chamber 37 equipped with doors 38. Spaces are provided atthe sides and top, respectively, of the chamber 37, and when the ovenunit is in use on the body 1, it will be .manifest that the propermanipulation of the ventilators 12 Willv permit escape of the productsof combustion so as to give rise to adequate circulation of heat aboutthe chamber 37, and yet, by virtue of the venti lators 12 having theguards 23, Wind is prevented from interfering with the operation of thestove in the open.

The outer Wall and top flange of the pot unit 33 are constructedsimilarly to the outer Walls of the oven unit 32, and the pot unit isalso provided with a flange 3, and with the protected ventilators 13 and1a; the latter being designed to serve the function ascribed to theventilators 12 of the oven unit. Permanently secured in the unit 33 is apot 10, spaced from the side Walls of the unit for the circulation ofheat, and equipped With a removable flanged cover 1. The pot unit 33 isused on the body 1 when the frying pan unit 30 and the oven unit 32 areidle. This interchangeable capacity of the three units described, Willbe appreciated as an important advantage When it is stated that thestove is especially adapted for use as a part of a circus or camp outt,and that it takes up but little space in storage or in use. It is alsoto be noted that the construction as a Whole is light in uf'eight,simple and inexpensive, and that no parts are included such as areliable to get out of order after a short period of use.

Having described my invention, what 1 claim and desire to secure byLetters-Patent, is:

1.` 1n a vapor or gas stove, the combination of a stove casing havingventilation openings, and interior guards closed at their sides and openat theirl ends, and eX- terior regulating means complementary to' saidopenings.

2. A cooking unit for use on a stove of the character described,including an exterior casing having an opening in its bottom Wall and adepending iiange surrounding the said opening'and the casing also havingvent openings, interior guards opposite and complementary to saidopenings and closed at their sides and open at their ends, exteriorregulating means also opposite and complementary to said vent openings,and a compartment closed at its bottom and adapted to be charged withsubstance to be cooked; the saidcompartment being arranged in and fixedto the easing and separated therefrom by an intervening space incommunication with the opening in the bottom Wall of the casing and alsoin communication With said vent openings.

In testimony whereof l Vhave hereunto set my hand in presence of twosubscribing Witnesses.

BENJAMIN F. GOLLMAR.
